Dometic VacuFlush Vacuum Generator | 317775212 | Low-Profile | 12V

Restore reliable vacuum flush operation to your Dometic VacuFlush RV toilet system with the Dometic 317775212 Low-Profile Replacement Vacuum Generator (12V). This genuine Dometic OEM vacuum generator is the heart of the VacuFlush system — creating the vacuum pressure that actually pulls waste from your toilet to your holding tank. When the generator fails, the entire VacuFlush system stops working; this is the critical component to replace when your existing pump is damaged, weak, or non-functional.

How VacuFlush Vacuum Generators Work

VacuFlush toilet systems are fundamentally different from gravity-discharge or pedal-flush toilets. Instead of relying on water flow or gravity to move waste, VacuFlush uses negative pressure (vacuum) to actively pull waste through the lines to the holding tank. That gives the system several real-world advantages — less water usage, more flexibility in waste line routing, and the ability to send waste UP or laterally rather than relying on downhill flow.

The vacuum generator does the work that makes all of this possible:

• Generates vacuum pressure in the system between flushes
• Stores vacuum in the polyethylene tank until ready for use
• Activates on flush to pull waste from the toilet to the holding tank
• Re-pressurizes automatically between flushes for the next cycle

If the generator fails, the entire VacuFlush system goes down — you can't flush, the toilet doesn't drain, and the system becomes non-functional until the generator is repaired or replaced.

Common Failure Symptoms

Common reasons to replace the vacuum generator include:

• Toilet won't flush — no vacuum being generated
• Weak flush performance — pump runs but doesn't develop adequate vacuum
• Pump runs constantly — system can't hold vacuum, pump keeps cycling
• Unusual noises from the pump or tank area
• Visible damage to the pump housing, tank, or wiring
• Vacuum leaks from the tank or pump assembly
• Electrical failure — pump doesn't respond to flush command

Before assuming the generator has failed, rule out simpler issues — wiring connections, power supply, fuses, control board, or vacuum leaks elsewhere in the system. These can mimic generator failure symptoms.

Low-Profile Design for Tight Mounting Locations

The 317775212 features a low-profile design — important for RV applications where mounting space is at a premium. Combined with the rotatable mounting configuration (pump and tank can be turned to fit your mounting location), the 317775212 fits into tight spaces that other vacuum generators simply can't.

Rotatable Vacuum Pump and Tank

Real-world installation flexibility:

• Vacuum pump can be turned to fit your mounting location
• Polyethylene tank can be turned to fit your mounting location
• Adaptable to multiple mounting orientations — important for retrofit installations where the original generator's exact orientation may not be available

Durable Polyethylene Tank

The vacuum storage tank is built with durable polyethylene construction:

• Resists corrosion in the moisture-heavy vacuum environment
• Lightweight compared to steel alternatives
• Long service life when properly installed
• Engineered specifically for VacuFlush vacuum holding

Plug-and-Play Wiring

The 317775212 features plug-and-play wiring — designed for direct replacement of the original vacuum generator without splicing or modifying existing wiring. That makes installation cleaner and more reliable than aftermarket alternatives that require electrical work.

What's Included for Installation

The kit ships ready for installation:

• Vacuum pump
• Polyethylene vacuum tank
• Lubricant pack
• Mounting spindles

12V DC Operation

The 317775212 operates on 12V DC — standard RV electrical, no special inverter or AC power required. Compatible with the wiring already in place on your existing VacuFlush installation.

Made in the USA

The 317775212 is manufactured in the USA — a meaningful provenance credential for buyers who specifically look for domestic manufacturing in critical RV components.

Multiple Part Number References

This same vacuum generator is referenced under multiple identifiers depending on the supplier or catalog:

• 317775212 (primary / legacy Sealand number)
• 9108554945 (Dometic SKU)

Both refer to the same product — either may appear depending on the supplier or catalog generation.

⚠️ Professional Installation Required

VacuFlush vacuum generator installation involves working with the toilet system's plumbing connections, vacuum lines, electrical wiring, and waste holding tank interface. Improper installation can cause vacuum leaks, system performance issues, or waste line failures. Installation should be performed by a qualified RV service technician with experience working on VacuFlush systems.
